        [Fact(DisplayName = "Test Demo Display Name")]
        [Trait("Category", "Internal")]
        [Trait("Category", "All")]
        public void Demo()
        {

            // I like to get the DisplayName 'Test Demo Display Name' here(inside this function) for    furthur processing.


        }

I like to get the DisplayName 'Test Demo Display Name' here(inside function) for further processing. How to do that? I know there are some option to get the Traits details using the TraitsHelper class. Is there any similar approach available for Facts attribute as well.

I'm not sure if xUnit has some specific mechanism to help you do this, but you can easily write your own helper to do this.

using System.Diagnostics;
using System.Linq;

static class XUnitHelper
{
    internal static string FactDisplayName()
    {
        var frame = new StackFrame(1, true);
        var method = frame.GetMethod();
        var attribute = method.GetCustomAttributes(typeof(Xunit.FactAttribute), true).First() as Xunit.FactAttribute;

        return attribute.DisplayName;
    }
}

Inside your unit test method, call XUnitHelper.FactDisplayName(). Of course this won't work if there is any nesting - for example, if you call this helper in another method which is itself called from the unit test method decorated by Fact. To handle a case like that, you'd have to write more complicated code which traversed the stack (in fact, that's why the 1 is passed to the constructor of StackFrame; we want to skip past the stack information for the helper method itself).

  • Currently i am using below code for getting the 'DisplayName'. I am looking for any specific xUnit functions for doing this. MethodBase method = MethodBase.GetCurrentMethod(); FactAttribute attr = (FactAttribute)method.GetCustomAttributes(typeof(FactAttribute), true)[0]; string nameForReport = attr.DisplayName; – Hashili Feb 04 '20 at 08:27
